Application filed December 17, 1914. Serial No. 877,718.

To all whom it may concern:

Be it known that I, JAMES E. SHEAFFER, a citizen of the United 'States, residing at Burnham, in the county of Miffiin and State of Pennsylvania, have invented a new and useful Hydrocarbon-Burner, of which the following is a specification.

- The present invention appertains to hydrocarbon or liquid fuel burners, and aims to provide a novel and improved'appliance of that character.

This invention contemplates the provision of a hydrocarbon'burner'of unique construction, to enhance the utility and the efii- .ciency thereof, and whereby the fuel will be thoroughly atomized and admixed with air, to provide a highly combustible mixture. It is also the object of the invention,'to provide a hydrocarbon burner of such construction, as to enable the air to be admitted or introduced in a novel manner, for thoroughly mixing and agitating the fuel and air, and whereby the'supply of air'may be regulated.

It is also within the scope of this invention, to provide a hydrocarbon burner of the nature specified, which will be comparatively simple, compact, non-encumbering andinexpensive in construction, as well as being convenient, practical and serviceable in its use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the comthe details-0f construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made Within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in its preferred embodiment in the accompanying drawing, wherein 5 Figure 1 is an elevation of the improved 1 burner, partly in section. Figs. 2 and 3 are cross sectional views taken on the lines 22 and,33, respectively, of Fig. 1.

In carrying out the invention, there is provided a frusto-conical or tapered casing or body 1, having its largest end disposed forwardly, and having the inner integral nozzles 2 and 3 between its ends. The nozthe nozzle 2 and projecting into the basal or rear portion. of the same. The forward end or tip of the nozzle 2 projects through the forward or largest end of the casing 1. The rear or smallest end of the casing 1 is provided with a reduced portion or boss 1, forming a 'rearwardly facing shoulder 5, and the casing 1 is also provided with three annular series of slots or air inlets 6, 7 and 8. The slots 6 are disposed between the basal portio'nof the nozzle 2 and the forward end of the casing, and the slots 7 are dispos'edbetween the basal portions of the nozzles 2 and 3, while the slots 8 are disposed between the basal portion of the nozzle 3 and the rearend of the casing 1. The forward end of the casing l is provided with an outturned -annular flange 9 having the annular lip or rim.10.

A refractory discharge nozzle 11 which is of frusto-conical or forwardly tapered form,

has its largest or basal end seated against the forward end of the casing 1, and provided with an outstanding annular flange 12 fitting within the lip or rim 10 of the flange 9, and a ring or annulus 13 of angular cross section is fitted over the basal portion and flange 12' of the nozzle 11 to cotiperate with the flange 9 and its lip or rim 10 for clamping' the basal flange 12 of the nozzle 11 in place. Bolts or other securing elements 141 are engaged through the ring or annulus 13 and the flange 9, for clamping the parts together and whereby when the bolts 14 are loosened and removed, the parts may be separated.

A frusto-conical or tapered shell or sleeve 15 isxmounted for rotation upon the casing or body 1, and is preferably provided with an outstanding handle or finger piece15 for enabling theshell 15 to be readily swung to open and closed positions.

The oscillatory movement of the shell 15 is preferably limited by means of an arcuate slot 16 provided in the shell 15, and a stud or lug 16 secured to the casing 1 and extending through the slot 16. The shell 15 provides an air regulator, it being provided with three annular series of slots or openings 17 18 and 19 coiiperating with the respective slots 6, 7 and 8 of the casing 1 to be brought into'and out of registration therewith as the 1 shell'or' regulator 15 is swung back and ..ing 1 and bears against the rear or smallest end of the shell 15 for mounting'the same rotatably in place upon the casing. When the nut 20 and stop or lug '16 are removed, the shell or regulator 15 may be moved off of the casing 1.

A tubular steam or pressure fluid nozzle 21 has a portion 22 between its ends threaded through the'smaller end of the casing 1 and having its tip 23 projecting forwardly within the casing into the basal portion of the nozzle 3, the nozzle 21 having a restricted or contracted portion 24; in rear of the tip 23, and also having an oil or liquid fuel inlet or branch 25 immediately in rear of the restricted portion 24 and arranged at an acute angle to the nozzle 21.

The nozzles 21, 3, 2 and 11 are co-axial and arranged in a longitudinal series, with the tip of the nozzles 21, 3 and 2 projecting into the basal portions of the respective nozzles immediately in advance thereof.

The nozzles 21, 3, 2 and 11 are also increased in'size in succession. The parts of the burner 'may be readily cast from metal, or formed in any other suitable. manner, and

,may be readily assembled with one another,

as well as being readily separable for purpose of-cleaning, repair or replacement.

In use, the steam or pressure fluid and liquid fuel or oil pipes .are attached to the nozzle 21 and branch 25, respectively. Then,

as the steam or pressure fluid is admitted through the nozzle 21 it will be directed axially forward through the nozzles 2, 3 and 11 successively, and the passage of the steam through the nozzle 21 will draw a jet or stream of oil or liquid fuel through the branch 25, it.being noted that the steam in passing through the restricted or contracted portion 2 1 of the nozzle 21 will create a suction extending through the branch 25 for causing the fuel to be drawn into the nozzle 21 and casing 1 with the steam. Now, when the steam is discharged from the nozzle 21 it will atomize thefuel, and the mixture benozzle 3 through the nozzle 2, air will bev drawn inwardly between the nozzles 2 and 3 through the registering slots 7 and '18, and in a like manner, when the mixture passes from the nozzle 2 through the nozzle 11, air will be drawn through the slots 6 and 17 to flow between the nozzles 2 and 11 to admix with the mixture discharged from'the nozzle'2. The final mixture is discharged from the nozzle 11 to support the flames, it.

being understood that the present burner may be employed for heating boilers, furnaces, and the like, or in any'other suitable capacity. I

Due to the construction of the present burner, streams of air will be admitted through the slots of the casing and'shell or regulator and will pass through the annular spaces between the concentric nozzles, to admix with the steam and atomized fuel, to'

thoroughly agitate and mix the steam,'air and fuel for providing a highly combustible mixture. The amount of air admitted into the casing may be regulated by swinging or adjusting the shell or regulator 15 to bring the slots thereof more or less out of registration with the slots of the casing 1.

' The present burner may not only be employed for burning liquid fuel, but may'also be employed for burning pulverized coal, and similar substances.

What is claimed is: A hydrocarbon burner embodying a 'cas ing having a nozzle therein projecting toward one end, said end of the casing hav ing an outturned annular flange provided with an annular l1p,a discharge nozzle hav- 1ng.1ts basal end seated agalnst said end of the casing and provided with an outstanding annular flange fitting within said lip, a ring" of angular cross section fitting over the basal portion and flange of the discharge nozzle, and securing elements engaged through said ring and first mentioned flange.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

JAMES E. SHEAFFER.
